To all whom t may concern:

Be it known that I, CARLOS WI'rrENMYnR,

a citizen of the United States, and residing at Detroit, in the county of Wayne and State 'of Michigan, have invented a new and Imture and humidity, which can be produced i at low cost, and which may be installed at a minimum of expense.

This invention consists of a coil of metal wire adapted to be connected into an electric circuit sufficient to heat the wire, a plug adapted to screw into the wall of the chamber in which the fuel is to be vaporized, and a nozzle to project liquid fuel onto hot wire.

It further consists in the details of construction illustrated in the vaccompanying drawing and particularly pointed` out in the claims.

In thedrawing, Fig. 1 is a side elevation of an engine provided with my improved fuel vaporizer. Fig. 2 is a central section of the vaporizer. Fig. 3 is a central section of a pump adapted for use with this vaporizer. Fig. 4 is a section on the line 4t-4t of Fig. 2.

Similar reference characters refer to like parts throughout the several views.

Fig. 1 shows an engine lhaving an intake manifold 2 and a carbureter 3 connected thereto. On the instrument board 4 is a switch 5 adapted to close the circuit between the wire 6 leading to the battery 7 and the grounded wire 8. A wire 9 leads from the battery to the vaporizer. The fuel may be obtained from any convenient source.` In the drawing, a suction pipe 10 for the hand pump 12 is shown to connect to the supply pipe 13 for the carbureter 3 and a discharge pipe 15 leads from the pump to the vaporizer, ball valves 16 with proper springs 17 being of well known construction.

The vaporizer consists of a hollow plug 19 adapted to screw into the wall of the intake manifold 2, a washer 20 being shown to give a good seat. A heating coil 21 is attached to the end of the plug and is preferably conical, the outer end 22 of the coil being turned yinward and extending out through an insulating core 23, the outer end being looped.` A threaded metal sleeve 24 screws into this core and metal washers 25 between the head 26 of the sleeve and the core grip the loop 30 at the end of the heating wire and the loop 27 at the end of the conductor wire 9. The pipe 15 extends through the sleeve 24, being insulated there- Lfrom by the` insulating sleeve 28, and the discharge end of this pipe is formed into a nozzle 29which sprays the tuel onto the heating coil 21.

When the engine is to be started under conditions which render startingf diiiicult,

suchl as low temperatures which preventV ready vaporization of the fuel, the switch 5 is closed to cause the current from the battery to heat the coil 21. When the coil is sufficiently hot, the engine is turned over by its starter and a spray of fuel is thrown onto the coil through the nozzle 29 and is immediately vaporized, drawn into the engine cylinders and exploded. This'is particularly of value when the use4 of kerosene and of low grades of gasoline, which vaporize quite readily in hot engines but do not readily vaporize when very cold.

While the use of this vaporizer in connection with an internal combustion engine alone has been described, the invention is not limited thereto but may be used wherever else liquids are to be vaporized, and the details and proportions of the vaporizer may be changed by those skilled in the art to adapt this invention to such other purposes without departing from the spirit of my 1nvention as set forth in the following claims.

. I claim 1. A vaporizer comprising a hollow base, an insulating corevtherein, a conical heating coil mounted on lthe base and projecting therefrom and having its outer end bent back to extend through said core, a nozzle mounted in said core and adapted to spray a liquid onto the coil, means to convey a liquid to the nozzle, and an electric conductor connected to the coil.

2. A vaporizer comprising a hollow externally threadedplug adapted to be screwed linto a threaded hole in the wall of a fuel inund moons to convoy lquh'l fue] to tho nozzlo, L sleeve screwed into the coro 'within which sleeve the nozzle is mom'xtonl, :mo n lo electric conductor oonnoolml to Suid ondv of the heating coil.

CARLOS WITTENMYER.
